Question

您好我已经尝试在我的选项卡片段中添加一个类并且它正在抛出一个错误，我一开始认为我是愚蠢的，因为我没有将活动添加到清单中但是在我做完之后没有＆＃39;工作。如何在清单顶部添加活动，以及抛出此异常的以下错误

ON：main

Process: com.androidbelieve.drawerwithswipetabs, PID: 14861 
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.androidbelieve.drawerwithswipetabs/com.androidbelieve.drawerwithswipetabs.BradClass}; have you declared this activity in your AndroidManifest.xml?

这就是我写活动的方式

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">

        <activity
            android:name=".LeagueOne"
            android:label="leagues"></activity>
        <activity
            android:name="com.androidbelieve.drawerwithswipetabs.BradClass"
            android:label="leagues"></activity>
                   <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Answer 1

将您的清单更改为：

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
       <activity
        android:name=".MainActivity"
        android:label="@string/app_name"/>

        <activity
            android:name=".LeagueOne"
            android:label="leagues"/>
        <activity
            android:name="com.androidbelieve.drawerwithswipetabs.BradClass"
            android:label="leagues">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />    
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
</application>

Answer 2

你的manifest.xml有些错误。

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
    </activity>

    <activity
        android:name=".LeagueOne"
        android:label="leagues"></activity>
    <activity
        android:name="com.androidbelieve.drawerwithswipetabs.BradClass"
        android:label="leagues">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

如果要将MainActivity用作luncher，可以将intent-filter移动到MainActivity块。

Answer 3

将您的清单更改为下面给出的清单，您将活动置于主要问题的活动之下，所有活动都应该单独声明。

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
      <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
        <activity
            android:name=".LeagueOne"
            android:label="leagues"></activity>
        <activity
            android:name="com.androidbelieve.drawerwithswipetabs.BradClass"
            android:label="leagues"></activity>
</application>
